Description

  The present invention relates to a support device for fixing to a window glass of an automobile. The support device includes a substrate that can be fixed to the window glass. The support arrangement of the support device is formed to hold the housing of at least one camera. Furthermore, the present invention relates to a window glass of an automobile to which such a supporting device is fixed.

  Patent Document 1 describes a support device disposed on a windshield of an automobile. For this purpose, the substrate of the supporting device is fixed to the window glass with an adhesive. The support structure for fixing the camera housing to the substrate includes a frame formed by integral casting with the substrate. A spring member in the shape of a B-shaped metal bar is provided on the frame, and this spring member presses against the opposing wall of the frame in a camera housing incorporated in the frame.

German Patent Application Publication No. 10 2008 050 320 A1 German Patent Application Publication No. 10 2011 121 003 A1 German Patent Application Publication No. 10 2012 101 781 A1 International Application Publication No. 2013/056331

  The object of the present invention is to produce a support device of the kind described above and a window glass of a motor vehicle having such a support device, which improves the positioning of at least one camera relative to the substrate and thereby Allowing the substrate to be positioned and secured to the window glass.

  This object is solved by a support device having the features of claim 1 and an automotive window glass having the features of claim 10. Advantageous embodiments with preferred developments of the invention are described in the dependent claims.

  The support device of the present invention having a substrate that is fixable to a window glass of an automobile, wherein the support structure is formed to fix the housing of at least one camera, and the support structure has at least one spring member. A spring member is formed so as to directly apply a pressure acting in a direction toward the substrate to a rod-shaped component that includes two holding members and is disposed on the housing and protrudes on the peripheral wall of the housing. . In other words, with respect to the arrangement of the support device 10 on the window glass of the vehicle, the camera housing is pressed in the direction of the window glass by at least one holding member. Accordingly, in the present invention, the visual field range to be provided on the window glass for at least one camera may be formed relatively narrow. This is because the size of the field of view cone or detection range of the camera is reduced depending on the degree to which the camera approaches the window glass. As the distance of the camera from the window glass is reduced by 1 millimeter, the diameter of the camera's viewing cone through which at least one camera senses its periphery is reduced by 5 millimeters at the window glass position.

  Therefore, in the black printing part provided on the window glass, which is used for optical shielding of the support device, the cut portion necessary for the field cone may be smaller. In addition, in a camera housing arranged relatively close to the substrate, the cover that covers the camera on the passenger compartment side may be correspondingly sized.

  Furthermore, this kind of fixation does not cause a force directly on the camera housing, but the pressure exerted by the holding member with the spring is only on the rod-shaped component protruding on the peripheral wall of the camera housing. Works. Thus, the support device allows for improved positioning of the camera.

  Preferably, the support arrangement includes three holding members, which are arranged on different sides of the receiving part of the support device provided for the camera housing. Such fixing of the camera housing to the three fixing points assigned to the receiving part and provided by the holding member results in a particularly good position definition of the assembled camera housing. Movement of the camera housing relative to the substrate, i.e. wobble, can thus be prevented particularly well. This is particularly advantageous because the position is stable and a clear and defined positioning of the camera with respect to the substrate and thereby positioning with respect to the vehicle window glass is particularly important in order to fulfill the functions performed by the camera. It is.

  The receiving part provided for the camera housing may in particular be substantially square because the camera housing may also have a substantially square bottom surface.

  The substrate may be provided with two different accommodating portions, each having three holding members assigned to each accommodating portion. In this case, two of both holding members may be assigned to the same accommodation portion. As a result, either a housing having two cameras, that is, a so-called stereo camera, or a housing having only one camera, that is, a so-called mono camera can be freely selected and fixed to the support device using each of the three holding members. Is possible. Nevertheless, the support device need only have a total of four holding members, whereby three holding members are assigned to each receiving part. Therefore, when the stereo camera is arranged on the support device, the holding member assigned to the accommodating portion provided for the mono camera remains unused. Similarly, in the case where the mono camera is arranged on the support device, the same holding member assigned to the accommodation portion for the stereo camera remains unused in the accommodation portion provided for the mono camera.

  By providing three holding members in each receiving part for the housing of at least one camera, the angle that at least one camera has with respect to the substrate and thereby with respect to the window glass is in particular Reproducible with high accuracy.

  Two of the three holding members may be arranged on the side of the receiving part, which side is at least substantially relative to the longitudinal side of the vehicle with respect to the arrangement of the support device 10 on the window glass of the vehicle. It extends in parallel. By fixing the two holding members to the two rod-shaped components, the orientation of the camera housing can be set unchanged with respect to the longitudinal direction of the automobile. When the two holding members arranged on the side surfaces of the receiving part are arranged so as to be aligned with the fixed rod-shaped component, a rotating shaft for the housing is advantageously produced. By this pivoting of the camera housing about the axis of rotation, the angle of the camera housing with respect to the substrate is then particularly easily and reliably achieved by fixing the third rod-shaped component to the third holding member of the three. Can be set.

  Preferably, each of the two holding members arranged on the side surface of the receiving portion has an insertion portion, and this insertion portion becomes a respective locking recess for each rod-shaped component. An installation direction extending at least substantially parallel to the substrate by the insertion portion is defined for the housing of at least one camera. Such an installation direction is advantageous because it is not necessary to apply too high pressure to the window glass when the camera housing is installed. This kind of improved mounting movement of the camera housing allows a greater working force to be applied during assembly parallel to the window glass without the risk of damaging the window glass. Particularly easy assembly occurs when the installation direction of the tilted window glass coincides with the tilt of the window glass. Therefore, when the housing is moved in parallel with the substrate, for example, the housing is basically mounted from top to bottom.

  The locking recess provides positive lock retention of the rod-shaped component, thereby providing positive lock fixation of the camera housing with the support device in the event of a collision. In other words, as long as the rod-shaped component is housed in the locking recesses of the two holding members, the locking recess prevents the vertical movement of the at least one camera housing in the automobile.

  It has been found that it is further advantageous if the installation direction indicates the forward direction of the vehicle with respect to the arrangement of the support device 10 on the window glass of the vehicle, and the insertion part of the two holding members is U with respect to the installation direction. It is formed to open in a letter shape or a V shape. Such formation of the insertion part is advantageous, for example, during a frontal collision of a motor vehicle. This is because in that case, the housing of at least one camera is securely held in the longitudinal direction of the automobile in which the insertion portion is tapered.

  Preferably, of the two holding members, the third holding member is arranged on the side surface of the accommodating portion, and the side surface is closer to the front part of the vehicle than the rear part of the vehicle with respect to the arrangement of the support device 10 on the window glass of the vehicle. In other words, the third holding member may be provided on the front side of the housing portion. That is, in that case, the side of the housing of at least one camera that faces this front side can be used here to provide a connection, etc., without the rod-shaped component getting in the way.

  It may be further advantageous if a recess or indentation is formed in the base part of the third holding member, into which a rod-shaped component projecting on the peripheral wall of the housing in the installation direction can be inserted. It is clear.

  The insertion of the rod-shaped component into the recess makes the camera housing particularly easy to assemble. This is especially true if the rod-shaped component projecting on the peripheral wall of the housing in the installation direction is longer than the two rod-shaped components provided on the side of the camera housing. Further, in order to facilitate insertion of the rod-shaped component into the recess, the rod-shaped component may be formed so that the tip is oblique or conical.

  On the other hand, the rod-shaped component that will be accommodated in the two locking recesses is preferably formed with a round and smooth surface, in order to establish as easy an installation as possible of the camera housing. ing.

  It has been found that it is further advantageous if the height of the third holding member is adjusted according to the inclination of the window glass of the vehicle and the detection range of at least one camera. Thus, by changing the height of the holding member, a support device that otherwise does not change can be used very easily in a mass production model of automobiles with different slopes of the window glass. This is particularly easy when the substrate and the substrate of the holding member formed by integral casting with the substrate are manufactured from plastic, for example, when the support device is manufactured by an injection molding method. That is, in that case, in the metal mold used for manufacturing the substrate, it is only necessary to use a replaceable insert, and the height of the third holding member can be defined using this insert. Therefore, it is not necessary to newly manufacture all molds for manufacturing the substrate. Rather, it is appropriate to apply only replaceable inserts that will be provided for the molding of the third holding member to the mold otherwise unchanged.

  In addition or alternatively, the spacer disposed on the first side of the substrate can be adjusted in height according to the slope of the window glass. Also here, when manufacturing substrates from plastic, replaceable inserts can be used, which differ in the height of the spacers corresponding to the inclination of the window glass as defined in the car production model. It will be. Therefore, an appropriate angle can be defined without depending on the inclination of the window glass existing in each mass production model of an automobile, and at least one camera can detect the periphery in the horizontal direction at that angle. To do.

  Preferably, the at least one spring member of the at least one holding member that serves to apply a pressure acting on the rod-shaped component in a direction towards the substrate is made of metal. The metal spring member is particularly elastic and robust. In particular, a simple leaf spring can be used as the metal spring member, and this leaf spring can be made of a single material in a small size and at a low cost. In addition, this type of spring member can be already arranged on the respective base of the holding member during the production of the substrate, especially at a low cost. This provides an advantage from a manufacturing point of view when mounting the support device and the camera housing on the vehicle. The mechanized installation of the spring member can be done, for example, via a swivel robot or other automated technique.

  The spring member advantageously comprises a fixing member that prevents the spring member from falling off the base of the holding member. For example, a latch formed like a notch can be provided, and this latch rebounds to its installation position when the spring member is moved, that is, in this case, in the state of the spring member arranged on the base of the holding member It is installed with the base.

  An aperture member that can be fixed to the substrate can be provided in at least one camera. Such a diaphragm member, for example, in the form of a lens hood, which can be detachably fixed to the substrate, enables the appropriate arrangement of the substrate having each diaphragm member depending on the equipment of the support device having one or two cameras. To. The diaphragm member can be fixed on the substrate by, for example, clipping. By detachably holding the diaphragm member on the substrate, a diaphragm member whose shape is adapted to each camera type can be used.

  Further, the material and surface of the squeezing member or the coating can be provided differently, which may be different from that of the substrate. Therefore, the diaphragm member is already detachably fixed to the substrate and can be used, and can be particularly well adapted to the intended use of the diaphragm member.

  Such a throttle member can be fixed to the substrate and may have a heating device. Thereby, it is possible to apply heat to the area of the window glass, which area will be de-fogged to ensure observation of the camera through the window glass. By integrating the heating device with the aperture member, it is possible to accurately apply heat to the area of the window glass where the objective lens of the camera is located. In addition, when a heat ray or the like is disposed in the throttle member, it is not necessary to provide the heat ray or the like in the window glass. This reduces the deformation of the window glass that would be provided depending on the equipment of the car with one or two (or zero) cameras and is therefore particularly advantageous.

  In addition, the throttle member can be replaced particularly easily when the heating device fails. Connecting the heating device of the throttle member to the electronic system can also be achieved particularly easily by providing a fixing means for the corresponding power distribution device on the substrate, through which the heat ray, etc. It can work with electrical energy supplied by the automotive electronic system.

  Finally, it is advantageous if the support device comprises at least one cover member removable from the substrate, which can be used to cover notches provided for cameras or other sensors in the substrate. It has become clear that. That is, if the support device is not equipped with a camera or another sensor, the cover member may be left on the substrate to cover the notch of the substrate. Thereby, the protection of the window glass from dust is guaranteed at the components arranged in the support device and at the installation position of the support device.

  Furthermore, in principle, a support device designed for holding the housing of the stereo camera can be used for holding the housing of the mono camera, and the notch provided for the second camera has at least It remains covered by one cover member. For reliable removal of the at least one cover member, a set breaking point is preferably provided.

  The window glass according to the invention of a motor vehicle is equipped with a glue in a precise position with the support device according to the invention. By placing the support arrangement of the support device in a precise position on the window glass, the housing of the at least one camera can at least surround the periphery of the vehicle using the at least one camera after installation of the window glass in the vehicle. It can be fixed to the window glass so that a specific area can be detected. In this case, the support arrangement provides an easy and inexpensive fixing of the housing of the at least one camera on the substrate of the support device, but at an angular position as provided at least for detecting the area around the car. to enable. In this case, a reliable retention of the at least one camera housing on the substrate is ensured and the relative movement between the camera housing and the support device is sufficiently prevented. This leads to a particularly precise fixing of the desired orientation of the camera optical axis relative to the car window glass. Therefore, the positioning of the camera on the window glass is improved by all the advantages of the support device according to the invention.

  The advantages and preferred embodiments described for the support device according to the invention also apply to the window glass of a motor vehicle according to the invention and vice versa.

It is a fragmentary perspective view of the lens hood before finally screwing using the holding latch formed by integral casting with the board | substrate of the support apparatus shown in FIG.

  FIG. 1 shows a plan view of a support device 10, which can be fixed to, for example, a window glass (not shown), which is a windshield of an automobile, whereby the camera is attached to the window glass. Can be placed. The support device 10 includes a substrate 12, and a first side surface 14 facing the window glass when viewed from the substrate is shown in FIG. FIG. 1 shows the second side 16 of the substrate 12 farther away from the window glass.

  A housing 18 is held on the substrate 12, and two cameras are arranged in the housing in the modification shown in FIG. 1. In this case, the first camera is in the left region 20 of the housing 18 with reference to FIG. 1, and the second camera is in the right region 22 of the housing 18 with reference to FIG. Holding members 24 and 26 are provided to fix the housing 18 to the support device 10, and the holding members are arranged on different side surfaces of the accommodation area of the support device 10 provided for the housing 18. The two holding members 24 are arranged on the side of the receiving part, which side extends parallel to the longitudinal side of the vehicle with respect to the arrangement of the support device 10 on the window glass of the vehicle. The two holding members 24 are formed in the same manner, and include a base 28 formed by integral casting with the substrate 12. Similarly, the 3rd holding member 26 arrange | positioned in the front side of an accommodation area | region regarding the arrangement | positioning of the support apparatus 10 in the window glass of a motor vehicle includes the base | substrate 30 formed by integral casting with the board | substrate 12. As shown in FIG.

  On the holding members 24, 26, respective rod-shaped components are fixed in the form of bolts 32, 34, 36 protruding on the respective peripheral walls 38, 40, 42 of the housing 18 (see FIG. 2). about). With respect to the arrangement of the support device 10 on the window glass of the vehicle, the arrow 44 presented in FIG. 1 indicates the direction of advance of the vehicle. Correspondingly, the first bolt 32 disposed on the left side of the housing 18 in the forward direction protrudes on the left peripheral wall 38. Correspondingly, the second bolt 34 projects on the right peripheral wall 40, and the front-side third bolt 36 projects on the front-side peripheral wall 42.

  By fixing the three bolts 32, 34, 36 to the corresponding three holding members 24, 26, the arrangement of the housing 18 and thereby the arrangement of the camera is relative to the substrate 12 and thereby the window glass of the car. On the other hand, it can be adjusted to a particularly good and accurate position. The angle of the optical axis of the camera with respect to the window glass can be defined particularly accurately and can be reproduced particularly well.

  A diaphragm member in the form of lens hoods 46 and 48 is assigned to each of the two cameras in the support device 10 shown in FIG. Each lens hood 46, 48 preferably interacts with a recess 52 provided in the substrate 12 via a holding shaft 50, 51 and is fixed to the substrate 12 by clipping or screwing (FIG. 3, see FIGS. 17, 30, and 31).

  The lens hoods 46, 48 can be equipped with a heating device, for example, in the form of a hot wire. Therefore, the lens hoods 46 and 48 can be easily replaced when the heater fails. In FIG. 1, a holder 54 is provided in the region of the support device 10 that is partially covered by the left side region 20 of the housing 18 (see FIG. 3), and supports the power distribution device via the holder. It can be fixed to the device 10. A power distribution device, also called a soldered power distributor, serves to supply electrical energy made available by the automobile to the heat rays integrated within the lens hoods 46,48. A soldered power distributor can be inserted and soldered through the notch 56 in the substrate 12 (see FIG. 3).

  In FIG. 4, the lens hoods 46, 48 can be seen from their side facing the window glass. Further shown in FIG. 4 is a spacer 58 disposed on the side 14 facing the window glass of the substrate 12. By fixing the height of the spacers 58, different window glass tilts in different mass production models of the vehicle can be taken into account so that the same support device 10 can nevertheless be used in different mass production models. Despite the different tilts of the car window glass, the orientation of the optical axis of each camera in the horizontal plane, and thereby the detection range of the camera, is guaranteed to be the same in different mass production models of the car.

  The spacer 58 may have a height of, for example, 1 mm when the support device 10 in which the substrate 12 extends parallel to the window glass is disposed on the window glass. The spacer 58 provides that the adhesive used to secure the support device 10 to the window glass, for example a polyurethane adhesive, has the same thickness.

  FIG. 5 shows a perspective view of the first bolt 32 protruding on the left peripheral wall 38 of the housing 18. The first bolt 32 is circular in cross section and has a smooth surface, so that the bolt can be easily inserted into the corresponding insertion part 60 of the assigned holding member 24 ( Compare FIG. 9).

  Similarly, FIG. 6 shows a second bolt 34 protruding on the right peripheral wall 40 and having a circular cross section at the end. The second bolt 34 is somewhat longer than the first bolt 32, and the second bolt 34 is provided with reinforcing ribs 62 to provide high stability to the bolt. The circular end of the bolt 34 can be easily inserted into the corresponding insertion portion 60 of the assigned retaining member 24 because of the smooth surface (compare FIG. 8). The bolts 32, 34, 36 may have a diameter of about 5 mm, for example. The length of the first bolt 32 may be about 6.5 mm.

  The third bolt 36 (see FIG. 7) protruding on the peripheral wall 42 on the front side of the housing 18 becomes conical toward the tip 64, so that the holding member 26 to which this bolt is assigned. Can be easily inserted into the corresponding receiving portion 66 (see FIG. 10). The third bolt 36 may have a length of about 18 mm.

  When the housing 18 is fixed to the support device 10 in the insertion portion 60 of the holding member 24 provided for the first bolt 32 and the second bolt 34, the bolts 32 and 34 are positively locked in a specific region. Each of the locking recesses 68 is provided. The locking recess 68 is semicircular in the longitudinal section in this specification.

  In order to secure the housing 18 to the support device 10, the housing 18 is mounted in the installation direction parallel to the substrate 12, the installation direction being presented in FIG. Correspondingly, the front third bolt 36 is pushed in the installation direction in a receiving part 66 formed in the third holding member 26 (see FIG. 10). In order to facilitate the insertion of the third bolt 36 into the corresponding third holding member 26, a recess 70 is formed in the base portion of the base 30 of the third holding member 26. In this specification, it extends to the first region seen in the installation direction.

  FIG. 11 shows how the second bolt 34 is inserted into the insertion portion 60 in the installation direction and how it is accommodated in the corresponding locking recess 68 of the holding member 24.

  From the cross-sectional view of FIG. 12, it is particularly apparent how the first bolt 32 is housed in the associated locking recess 68 formed in the base 28 of the corresponding holding member 24.

  From FIG. 13, when the bolts 34 and 32 fixed in the holding member 24 are accommodated in the locking recess 68, particularly how the pressure acting in the direction toward the substrate 12 is applied, respectively. it is obvious. That is, for this purpose, a substantially flat spring 72 is mounted on each base 28 of the two holding members 24 in an unloaded state, and this spring applies pressure to the respective bolts 32, 34. Add. The spring 72 is made of metal and has a length of about 30 mm and a width of about 5 mm, for example. It should be understood that the illustration of the spring in FIG. 13 (also in FIGS. 24, 27 and 28) is only schematic. This is because the spring exerts a force on the bolt in the direction of the substrate, so that the spring is bent with full interaction with the respective bolt 32, 34 and is located on the bolt.

  The curved leg 74 or the edge of the spring 72 installed on the base 28 of the holding member 24 may have a length of 3 mm, for example. The spring 72 more preferably has a loss prevention device in the form of a latch 76 that is shaped like a notch. The latch 76 can be installed in the region of the base 28 that is opposite the leg 74. In that case, the latch 76 acts as a securing member that ensures that the spring 72 remains in the insertion portion 60 of the retaining member 24.

  From FIG. 14, it is shown how the third bolt 36 (see FIG. 7) protruding slightly obliquely upward from the substrate 12 is arranged in the accompanying accommodating portion 66 of the third holding member 26. Is particularly clear. For this purpose, a roof 78 is formed in the end region of the base 30 at the rear in the insertion direction, and a tip 64 of the bolt 36 is located under the roof (see FIG. 15). The direction of the third bolt 36 is slightly oblique, so that the tip 64 is guaranteed to apply pressure to the roof 78 from below.

  Further, the spring 80 disposed on the base 30 of the third holding member 26 applies a pressure acting on the bolt 36 toward the window glass of the automobile (see FIGS. 1 and 16). The spring 80 assigned to the third holding member 26 is preferably formed of similar outer shape, dimensions and material, like the spring 72 assigned to the other two holding members 24.

  From the perspective view of FIG. 16, the arrangement of the two holding members 24 and the third holding member 26 provided on the side of the housing portion for the housing 18 on the substrate 12 is particularly clear. From FIG. 16, it can further be seen that another holding member 82, which is similar to the right holding member 24 in FIG. . Through the use of the holding members 24, 82, 26, on the support device 10 shown in FIG. 16, the housing 84 can fix the camera, which housing contains only one camera and is therefore mono It is formed as a camera (see FIG. 19). Again, in that case, the two holding members 24, 82 are arranged in a receiving part assigned to the side surface of the housing 84, which side surface extends parallel to the longitudinal side surface of the vehicle.

  In particular from FIG. 16 another component of the support device 10 is recognized. As such, the frame 86 is integrally formed with the substrate 12, and the frame serves to fix the rain sensor and the optical sensor. The support device 10 has a notch 88 provided for installing a fog sensor assigned to the rain sensor and the light sensor in the forward direction as viewed forward from the frame 86. If the support device 10 is not equipped with a rain sensor and a light sensor, the area 90 (see FIG. 16) surrounded by the frame 86 remains closed by a cover member in the form of a dummy cap 92 (see FIG. 16). 1). In particular, the dummy cap 92 may be formed so as to be removable from the substrate 12 by being removed from the support device 10.

  Four further fixing bolts 94 are arranged on the substrate 12, and the bolts are preferably formed integrally with the substrate 12. The fixing bolt 94 serves to fix a cover cap (not shown) of the support device 10, and the substrate 12 is covered toward the passenger compartment using the cover cap. The cover cap (not shown) can be moved in the longitudinal direction of the automobile along the fixing bolt 94, so that the installation tolerance of the window glass and roof liner and the adhesion tolerance of the support device 10 to the window glass should be adjusted. Can do. In this case, the cover cap can be moved from the central position, for example by 3 mm towards the front of the car or towards the rear of the car.

  Further provided within the support device 10 are a plurality of expansion joints 96 that serve to relieve the tension generated following the heat exposure. An arrow 98 (see FIG. 1) located on the substrate 12 presents the center of the car labeled Y0 in a lateral direction and places the support device 10 exactly on the window glass relative to this center. Make it possible.

  In particular, it can be seen from FIG. 16 that a plurality of cable clips 100 are preferably arranged on the substrate 12, which facilitates the laying of cables for the power supply of, for example, rainfall sensors and optical sensors. To do. Further, in the present specification, a stopper 102 is disposed on the lens hoods 46 and 48, and one of the stoppers is in close contact with the peripheral wall 42 on the front side of the housing 18 in the housing 18 installed in the support device 10. (See FIG. 1). When the housing 84 of the mono camera is installed on the support device 10, the other stopper 102 out of the two is in close contact with the housing 84 on the front side. The stopper 102 facilitates checking whether the housings 18 and 84 have reached the installation positions of the housings held by the three holding members 24, 26, and 82 in the respective receiving portions.

  From the cross-sectional view of FIG. 17, it can be recognized particularly well how the lens hood 48 is arranged on the substrate 12 of the support device 10.

  In particular, it can be seen more clearly from FIG. 2 that the housing 18 may have a recess 104, which is necessarily an installation space for the housing 18 as compared to the overall rectangular shape of the housing 18. The need for can be less. As such, for example, the indoor rearview mirror, the rain sensor, and the optical sensor can be easily fixed by the support device 10 by the recess 104. In addition, the camera housing 18 preferably has a stepped portion that allows the power distribution device, such as a soldered power distributor, and the holding member 82 to be more easily stored under the housing 18.

  The substrate 12 is preferably provided with a cut portion 106 in which condensed water may accumulate (see FIG. 16). Thereby, the lenses of the respective cameras stored in the housings 18 and 84 are prevented from being fogged. More preferably, there is a drain groove in the substrate 12 for removing excess adhesive.

  The camera housed in the housing 84 shown in FIG. 19 can be placed on the support device 10 shown in FIG. 1, but in FIG. A support device 10 capable of performing Again, preferably, the two bases 28 of the holding member 24 on the side of the receiving part provided for the housing 84, which are arranged parallel to the longitudinal side of the motor vehicle, are formed by integral casting with the substrate 12. Has been.

  Similarly, the third holding member 26 serves to fix the front-side third bolt 36 protruding on the front-side peripheral wall 42 of the housing 84 (see FIG. 19). Again, the spring 80 shown in FIG. 18 serves to apply pressure acting on the third bolt 36 in the direction of the substrate 12.

  Furthermore, the spring 72 provided on the base body 28 of the other two holding members 24 brings about a pressure acting in this direction on the first bolt 32 and the second bolt 34 as well.

  FIG. 19 shows a housing 84 having three bolts 32, 34, 36 disposed on different sides of the same housing and protruding on the peripheral walls 38, 40, 42.

  FIG. 20 is an enlarged detailed perspective view of the first bolt 32.

  FIG. 21 is a perspective view of the third bolt 36 protruding on the front peripheral wall 42 having a conical tip 64.

  FIG. 22 is a perspective view of the base body 30 of the third holding member 26 assigned to the third bolt 36. Again, a recess 70 is provided in the base portion of the substrate 30, and the third bolt 36 is received in the recess when inserted into the receiving portion 66.

  FIG. 23 shows the third bolt 36 introduced into the accommodating portion 66 of the third holding member 26, and the tip 64 is disposed below the roof 78.

  From the sectional view of the third holding member 26 shown in FIG. 24, it can be seen how the spring 80 applies pressure to the third bolt 36.

  FIG. 25 is a perspective view of the second bolt 34 of the housing 84 introduced into the insertion portion 60 of the holding member 24.

  In FIG. 26, the perspective view of the 1st volt | bolt 32 accommodated in the 2nd holding member 24 among the two similarly formed was shown.

  From the cross-sectional view through the second holding member 24 assigned to the second bolt 34 shown in FIG. 27, the spring 72 applying pressure to the second bolt 34 is particularly clearly recognized.

  Similarly, the cross-sectional view of FIG. 28 specifically illustrates that the pressure exerted by the spring 72 is being applied to the first bolt 32.

  When viewed from the first side surface 14 of the substrate 12 facing the window glass shown in FIG. 29, it can be seen that a spacer 58 is also provided in the support device 10. Further, a lens hood 46 is shown clipped to the substrate 12. Furthermore, in FIG. 29, the notch 56 and the notch 106 are clearly visible.

  Further, FIG. 30 shows how the extension 108 of the lens hood 46 provides a detachable connection of the lens hood 46 to the substrate 12 in the region of the retaining latch 50 in the direction of the arrow 44. . In this case, the extension 108 is inserted into the holding latch 50.

  Finally, FIG. 31 shows a partial perspective view of the lens hood 46 before screwing with one of the two rear holding latches 51, the holding latch being a notch 106 provided in the substrate 12. It is arranged adjacent to. From this illustration, it can be seen that the latch hook 110 disposed on the base of the lens hood 46 can be engaged with the holding latch 51 by pivoting the lens hood 46 rearward toward the substrate 12.
